I back this game on Kickstarter so I had access to the closed beta. It's on Steam now, available as an early access title here. There's 2 game modes - Escape and Last Man Standing. I haven't really spent any time in the former but I'm really enjoying LMS. It's a battle royale style survival. Match starts, first player that makes it to the orb becomes the killer which is on a timer. Objectives for survivors is turn on these fuse boxes which cause the killer's time to drop faster. Once it's gone another orb appears and, again, first one there becomes the killer. The maps are a pretty decent size but as the match progresses the dome around continues to shrink. It's a fun game, I'd say more akin to Dead by Daylight in terms of the pace and actually hiding, because in Hide or Die you can really hide and fighting the killer just isn't an option. For $20 I'd say it's worth it.
There'll be more content added, maps and killers, and I'm confident it'll roll out since this is all original content so there's no threat of being destroyed in a lawsuit.
